Abstract: Together with Alexander Polishchuk, we prove that the (derived) moduli stack of complexes of vector bundles over a Gorenstein Calabi-Yau curve admits a 0-shifted Poisson structure. Many interesting Poisson varieties are components of this moduli stack, including Hilbert scheme of points on Fano surfaces, semi-classical limits of Feigin-Odesskii elliptic algebras, Log canonical Poisson structures on projective spaces, etc. We are able to prove several new results in classical Poisson geometry using this modular interpretation.
